Greenland Ice Sheet

The Greenland Ice Sheet is a vast body of ice covering roughly 80 percent of the surface of Greenland. The ice sheet is almost 2400 kilometers long in a north-south direction. The ice sheet, consisting of layers of snow compressed over more than 100,000 years, contains a valuable record about Earth’s past climates. The ice sheet glaciers continue to flow seaward and deposit sediment, but global warming has affected them. Warmer air temperatures have caused increased melting, resulting in a thinning of the ice sheet and faster glacial movement at the ice sheet edges.

On the grid in the image provided, construct a profile along line AB by plotting the thickness of the ice sheet where each isoline crosses line AB. Thicknesses of the ice sheet at A and B have been plotted on the grid. Connect all twelve plots with a line from A to B to complete the profile. [1]

Allow 1 credit if the centers of all ten student plots are located within or touch the rectangles shown below and all twelve plots are correctly connected with a line that passes within or touches the rectangles from point A to point B. The high point of the line must extend above 3000 m, but below 3500 m.

• Note: Allow credit if the student-drawn line does not pass through the student plots, but is still

• within or touches the rectangles.

• It is recommended that an overlay of the same scale as the student answer booklet be used to ensure reliability in rating.
